Abstract

Mathematics learning plays a crucial role in developing higher-order thinking skills, particularly students' creative thinking. This study aims to improve students' creative thinking and task management capabilities through the implementation of scaffolding learning strategies. The research method used was a quasi-experimental nonequivalent control group design. The research sample consisted of 60 students divided into two classes: an experimental class treated with scaffolding learning and a control class using conventional learning methods. The research instruments were a creative thinking ability test and a student task management questionnaire, which had been tested for reliability and validity. Data were analyzed using descriptive and inferential analysis. Statistical tests used included a t-test to understand the differences in results between the experimental and control classes, and an N-Gain analysis to see the increase in students' abilities. The research findings showed that students' creative thinking and task management abilities in the experimental class experienced a higher increase than in the control class. The N-Gain value of the experimental class was classified as medium to high, while the control class was classified as low to medium. Based on the research results, it can be concluded that the scaffolding learning strategy has a positive and significant effect on increasing students' creative thinking and task management abilities in mathematics learning.

Abstract

Tujuan penelitian ini adalah untuk melihat pengaruh penerapan model pembelajaran matematika realistik terhadap minat belajar matematika siswa. Penelitian ini merupakan penelitian quasi ekspriment (eksprimen semu) yang dilakukan di SMP Negeri 2 Rantau Utara T.A 2023/2024 pada pokok bahasan kubus dan balok. Kesimpulan dari hasil angket yang didapat dari siswa kelas VII, skor rata-rata minat belajar matematika siswa yang diberi perlakuan model pembelajaran matematika realistik lebih baik dibandingkan skor rata-rata minat belajar siswa yang diberi perlakuan model pembelajaran konvensional. Skor rata-rata siswa yang diterapkannya model pembelajaran matematika realistik yaitu sebesar 93,21 sedangkan skor rata-rata siswa yang diberi perlakuan model pembelajaran konvensioanl sebesar 72,93. Dalam perhitungan uji t diperoleh nilai t hitung pada taraf signifikansi sebesar 0,349 > 0,05 sehingga dapat disimpulkan ada pengaruh model pembelajaran matematika realistik terhadap minat belajar matematika siswa kelas VII SMP Negeri 2 Rantau Utara. Kata kunci: Model pembelajaran matematika realistik, Minat belajar matematika

Abstract

Research on mathematics learning has largely emphasized procedural mastery, while the development of students' creative thinking skills, particularly in madrasah settings, has not received optimal attention. Furthermore, empirical evidence regarding the effectiveness of the Realistic Mathematics Approach (RMA) in improving junior high school students' creative thinking skills is still very limited. The purpose of this study was to investigate how the use of the RMA affects students' original thinking skills in mathematics learning. This study used a pre-experimental design with one experimental group and no control group. The subjects were one class of students from various majors at MTs Hubbul Wathan Aek Nabara. Data were obtained through creative thinking ability assessments given before and during the implementation of the RMA, and supplemented by observations of student activities and engagement in the learning process. The application of the RMA significantly improved students' creative thinking skills, according to the research findings. The magnitude of the effect of the application of the RMA was calculated using Cohen's d effect size based on the difference in the average pretest and posttest scores. The calculation results showed an effect size of 5.65, which is included in the very large effect category. This shows that the implementation of PMR has a very strong impact on improving students' creative thinking skills in the Two-Variable Linear Equation System. This improvement reflects flexibility of thinking, fluency in generating ideas, and the ability to use various problem-solving strategies. This finding provides a theoretical contribution to strengthening the role of AMR in developing higher-order thinking skills, as well as practical implications for teachers in implementing contextual and student-centered mathematics learning.
